Formación

• Evidence of architectural or platform impact across frontend teams.
• Deep ownership of complex production systems built with React or React Native and TypeScript.
• Strong judgement in application boundaries, shared libraries, state management, performance and migration design.
• A track record of improving developer effectiveness, reliability or product quality through durable mechanisms.
• Practical experience diagnosing performance and correctness problems across web or mobile systems.
• Ability to influence technical direction through evidence, clarity and trusted execution rather than title.
• Clear communication that helps teams act on complex technical decisions.

Responsabilidades

• Set direction for frontend architecture across React, React Native and the shared monorepo.
• Own cross-team problems in platform capabilities, shared libraries, design-system foundations, tooling and developer experience.
• Lead decisions on boundaries, abstractions, state and data flow, performance, testing and migration strategy.
• Diagnose systemic rendering, bundle, runtime and release-quality problems and create durable fixes.
• Remain hands-on where implementation, prototyping or technical investigation is the fastest way to create clarity.
• Partner with product, backend engineering and QA on risks and decisions that cross team boundaries.
• Mentor senior engineers, raise review quality and make sound frontend judgement easier to reproduce across teams.
• Balance standardisation with team autonomy, avoiding platform work that creates more friction than leverage.
